  abstract = {{T}he conclusions of a collaborative study of the occurrence and importance of root-knot nematodes ({RKN}, #{M}eloidogyne$ spp.) and of their control agent, #{P}asteuria penetrans$, in parts of {E}urope, {A}frica, {S}outh {A}merica and the {C}aribbean are presented. {R}oot-knot nematodes were estimated to reduce the yields of a wide range of horticultural crops by greater than 25% in {E}cuador, {M}alawi and {T}anzania, and by ca 10% in {T}rinidad and {T}obago. {T}he greatest proportion of infected crops were observed in {E}cuador (205 of 207) and the least in {T}rinidad and {T}obago (70 of 174). {T}he mean gall index was greatest in {E}cuador (5.5). {L}evels of galling were least in {S}enegal (1.6), even though 89% of crops were infested and virulent #{M}. mayaguensis$ was widespread. {I}n all countries, #{M}. incognita$ and #{M}. javanica$ were the most abundant species, but #{M}. hispanica$ occurred widely in {B}urkina {F}aso, even in newly cultivated areas in the {S}ahile. {S}everal new esterase phenotypes were detected, especially in {E}cuador and {M}alawi. {J}uveniles ({J}2) collected from the soil during the surveys were examined for attached spores of #{P}. penetrans$. {I}t was widespread (20 to 60% of {RKN} populations), except in {M}alawi and {T}anzania (less than 10% were infected), and was found for the first time in {C}rete ({G}reece). {G}enerally, less than 50% of the {J}2 carried spores. {T}he occurrence of #{P}. penetrans$ was sometimes correlated with soil type e.g., in {S}enegal it was least frequent in sandy soils. {L}aboratory assays of the binding of spores of isolates of #{P}. penetrans$ to populations of {RKN} were sometimes almost as great as those between species. {I}n microplot trials in which an "exotic" isolate of #{P}. penetrans$ was introduced (ca 10(sup 3) spores per g soil), its incidence was not increased by increasing the frequency or intensity of the growing of {RKN}-susceptible crops...
